WINDOW-SCREEN.

SPECIFICATION forming pa rt of Letters Patent No. 278,006, dated May' 22, 1883. Application filed March 16, 1883. (No model.)

' To all whom it may concern:

Be it known that I, PHAREs W. FRY, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Window-Screens;and I do hereby declare the 'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the aceompanyin g drawin'gs, and toletters or figures of reference marked thereon, which form a part of this specification.

This invention relates to window-screens which are adjustable to fit windowsof different widths; and it consists, mainly, in making one of the end pieces of the frame movable toward the other in guides formed by bifureating the portions of the top piece and bottom piece which are nearest said movable end piece, and combining therewith bracin g-pieces, which are secured within said bifurcated portions and adapted to be shortened at will.

It also consists in the peculiar construction and combination of parts, as hereinafter particularly set forth and claimed.

In the accompanyingdrawings, Figure 1 represents a vertical longitudinal section through the screen-frame when extended to its utmost limit. Fig. 2'represents a similar view when the pivoted braces have been turned out and the movable end pieceslid in and fastened preparatory to reducing the size of the frame; and Fig. 3 represents a front elevation after the frame has thus been reduced, the removed parts being indicated by dotted lines.

A designates the wire screen, which is attached to the frame by easily-removable tacks a. Said frame consists of a fixed upright end piece, B, a movable upright end piece, B, and the intervening top pieee,'B and bottom piece, B These four pieces are held together by screws 11 and I), which are easily removable. The top piece and bottom piece are deeply mortised from near their middle points to the end of each, which is in proximity to the movable end piece, B, thus forming guideways, which receive teuons b formed on the upper and lower ends of said movable end piece. When its fastening-screws b are removed, this end piece may be slipped back in said guideways until the frame fits the window, the protruding ends of the top piece and bottom piece being cut away, and the screws 1) again turned into the soft wood of the frame, so as to fasten the movable end piece in its new position. In order to fill out the frame, and to adequately brace the said movable end piece, I pivot by means of screws 0 two movable bracing or filling pieces, 0, in the mortised spaces behind the said end piece in the upper and lower pieces, respectively. When these filling or bracing pieces 0 are parallel to the top piece, B and the bottom piece, B they brace the end piece, B, and fill openings which would otherwise be left in the frame. The inner or rear ends of these pieces 0 are beveled at c, and rest against correspondingly-beveled shoulders d,

This construction braces said filling-pieces O and holds them in place, while allowing them to be turned in one direction. so that their outer ends may be trimmed off to correspond to the contraction of the frame. The frame is made large enough to fit the largest size window. When it is to be applied to one of smaller size, the proper measurement is taken, the screws 1) at the movable end of the frame are removed, the filling or bracing pieces G are turned on their pivots into the position shown in Fig. 2, theirsquare ends are trimmed oii' to a suitable extent, the end piece, B, is moved to its new position and there fastened, as stated, the wire screen, which has been 1mand the excess of wood and wire is trimmed off. The frame is then in condition to be applied and used. The ends of the frame are preferably set into upright strips or guidepieces D, which are attached to the windowframe, and have a tongue-and-groove'connection with the ends of the screen-frame. They enable the screen to be attached on the inner side of the window-frame, instead of being attached thereto in the place of the lower sash, as is now generally the case.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- r 1. A window-screen frame having a movafastcned to allow this shifting, is rcfastened,

formed in said top piece and said bottom piece. h
